Abstract

The invention discloses a motor truck scale weighing platform position detection and calibration device, which comprises a base, a weighing platform and a control device, wherein the base is providedwith a foundation pit, the weighing platform is arranged in the foundation pit, a weighing sensor is arranged between the weighing platform and the bottom of the base, and a detection and calibrationmechanism is arranged in the circumferential direction of the weighing platform; a reference plate corresponding to the detection and calibration mechanism is arranged on the side wall of the foundation pit, the detection and calibration mechanism comprises a distance measuring device and a distance calibration device used for adjusting the distance between the edge of the weighing platform and the side wall of the foundation pit, and the distance measuring sensor and the distance calibration device are both electrically connected with the control device. According to the invention, an operator can obtain the real-time data of the distance between the periphery of the weighing platform and the side wall of the foundation pit according to the distance measuring device, and once the positionof the weighing platform deviates, the operator can adjust the position of the weighing platform in time by controlling the distance calibration device, so that problems can be found and adjusted intime; manual on-site inspection and adjustment are not needed, time and labor are saved during adjustment, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of truck scales, in particular to a position detection and calibration device for a weighing platform of a truck scale. Background technique [0002] The truck scale, also known as the ground scale, is a large scale set on the ground. It is usually used to weigh the tonnage of the truck. It is the main weighing equipment used for bulk cargo measurement in factories, mines, and merchants. Existing truck scales usually include a base and a weighing platform. The base is provided with a foundation pit, the weighing platform is arranged in the foundation pit, and a weighing sensor is arranged between the weighing platform and the bottom of the foundation pit. When the vehicle is on the weighing platform, the weight of the vehicle can be measured through the load cell. [0003] When the truck scale is in use, it is usually required that the weighing platform is located at the center of the foundation pit, and th...
